Hello all,
The cabal/cabal-install bug tracker seems to be down, so I'm not sure if
this is a known issue or not... When playing around with JHC earlier I
ran into the following errors:
$> cabal --version
cabal-install version 0.10.2
using version 1.10.2.0 of the Cabal library
$> cabal install --dry-run --jhc --verbose base
Reading available packages...
Resolving dependencies...
cabal: internal error: impossible

$> cabal install --dry-run --verbose base
Reading available packages...
Resolving dependencies...
cabal: Distribution/Client/Dependency/TopDown.hs:171:37-73:
Non-exhaustive patterns in lambda
I've seen that problem before, though I can't recall where off-hand.
Anyone know if this (a) has been reported, (b) has been fixed?
